The beam is used in a railroad yard for loading and unloading cars. If the maximum anticipated hoist load is $12 \mathrm{kip}$, select the lightest-weight steel wide-flange section from Appendix B that will safely support the loading. The hoist travels along the bottom flange of the beam, $1 \mathrm{ft} \leq x \leq 25 \mathrm{ft}$, and has negligible size. Assume the beam is pinned to the column at $B$ and roller supported at $A$. The allowable bending stress is $\sigma_{\text {allow }}=24 \mathrm{ksi}$ and the allowable shear stress is $\tau_{\text {allow }}=12 \mathrm{ksi}$.

The cable will fail when subjected to a tension of $2 \mathrm{kN}$ Determine the largest vertical load $P$ the frame will support and calculate the internal normal force, shear force, and moment at the cross section through point $C$ for this loading.
